Ok.. so I'm trying to hook up an accessory to turn on when i hit the unlock button, off when i lock the doors. Basically, I want it to share the dome light's power so it follows the same routine. I tried hooking into the dome light fuse in the fuse box under the driver seat only to find out that the fuse is getting constant power. Where do I have to hook into? How can I get this to work the way I want it to?
